China's ice and snow industry is transitioning from its early development stage to a new phase of high-quality development. This study retrieved articles from core journals in the China National Knowledge Infrastructure (CNKI) database published between 2015 and 2025, using "ice and snow sports" and "industry" as keywords. After screening, 169 articles were included and systematically reviewed using thematic analysis. The results show that China's ice and snow industry faces management challenges including a "top-heavy" industrial chain (weak downstream links), unbalanced regional development, a shortage of interdisciplinary talent, insufficient core technologies, superficial industrial integration, and high pressure for green development. The study proposes solutions such as improving the industrial chain integration mechanism, optimizing spatial layout, building a multi-level talent cultivation system, strengthening technological innovation, deepening "ice-snow+" integration, and improving the standardization system, thereby providing a theoretical reference for the high-quality development of the ice and snow industry.

Rapid urbanization and the continuous improvement of the land expropriation policy system have led to a continuous expansion of the landless farmer population, making their social security a crucial and unavoidable issue in the process of achieving common prosperity. This paper takes the currently effective social security policy texts for landless farmers in China as the object of study, employs grounded theory for three-level coding analysis, and constructs a theoretical model of the policy design logic. Based on this, the study found that the design of social security policies for landless farmers encompasses a complete logical loop, from target identification to implementation and operation, and then to external support. These three aspects are progressive and internally coupled: the policy design takes a "system for strictly and precisely defining beneficiaries " as its logical starting point, ensuring targeted allocation of resources through standardized and comprehensive target identification principles, multi-layered and dynamic identification and implementation processes, and differentiated and precise assistance strategies; it uses a "layered and diversified implementation system" as its operational hub, embedding flexible, diversified, and differentiated institutional arrangements in the payment, fundraising, operation, and disbursement stages to form an incentive-compatible operating mechanism; and it uses a "comprehensive and multi‑tiered support system" as its external support.

This study selects sample data of China's A-share listed companies from 2011 to 2023 to analyze the relationship and mechanism between supply chain stability and the development level of new quality productivity. The results show that supply chain stability is positively correlated with new quality productivity, that is, a stable supply chain contributes to the cultivation of new quality productivity. Heterogeneity analysis indicates that this positive impact is more significant in enterprises with high supply chain concentration and high financing constraints. This study enriches the research on the influencing factors of new quality productivity and the economic consequences of supply chain stability, and has certain practical reference significance.

The digital China initiative, leading sports nation initiative and healthy China initiative together with the cultural and tourism integration has set up a basis for the development of outdoor sports and tourism in terms of policies. With the digital economy driving more change, people's need for outdoor entertainment is not just about seeing things around them; it is becoming more individualized, immersive, secure and interactive. But there also are short-comings: Information is not symmetrical, supervision of safety is insufficient, products all look the same, and it's hard to match supply and demand. And it is also important tool which could deal with the supply problem. Research about existing digital sports, smart tourism, and outdoor sports industry is still very scattered and no one has carried out in-depth study of the connections between digital empowerment, resource development, sports tourism integration. The paper carries out an organized literature review to gather releas: In this paper we try to create a theoretical frame covering the areas of technologic supply, resources' attribute and integrative ways in industries. Theoritically can help us understand how value is created for sport tourism destination in the digital economy. Practically, it is beneficial to help local governments, scenic areas, outdoor sports enterprises and other units in carrying out resource allocation, product creation, smart management etc., so as to build an efficient high-quality outdoor sports industry system.

The construction of large-scale sport stadiums has become more apparent recently for urban growth, though the economic and social consequences remain unevenly distributed among local community. This paper examines three cases—SoFi stadium in Inglewood, California; Tottenham Hotspur Stadium in North London; and the Beijing National Stadium—to analyse how stadium construction shape urban economic growth, social equity, and governance through the lens of sports management and urban development theory. Drawing on stakeholder salience theory, gentrification studies, Community Benefits Agreement research, post-event venue utilization scholarship, and public-private partnership governance, the paper argues that the negative outcome associated with stadium construction are due to governance framework rather than the projects themselves. The finding suggests that future mega-project development need to have more equitable stakeholder engagement, stronger community benefits protection system, and financial feasibility grounded in operational practicality rather than political symbolism. Together, sports venue development can serve as tools for urban modernization and progress, but only when they prioritize long term stability for the residents over economic and cultural ambitions.

The changing demographic trend in China towards the ageing population has brought about a deep-rooted demand for long-term eldercare. At the same time, the integrity of the traditional family caregiving system has been compromised, which case, it has been fueled by the reduction in the size of households, domestic migration, and changing values in society. As a result, the idea of helping the elderly to age at home is now a crucial social policy goal. The paper will examine how effective the experimental Long-Term Care Insurance (LTCI) systems in China have been in promoting this purpose and will map out the processes that will support this shift in an orderly fashion. Combining up-to-date policy guidelines with recent empirical evidence, the study segregates four key areas, namely: provision of professional care, informal household support, structural living conditions, and extended intra-family spillover consequences. Current data show that LTCI promotes aging in place by stimulating the community-based interventions expansion. It has been proven to reduce the burden on family caregivers, reduce the reliance on costly institutional care, and enhance the autonomy of the elderly. Remarkably, these results are largely regionally heterogeneous as local differences between the policy structure, funding, and the execution of the services are present. After all, LTCI is more than mere monetary rewards; it is an essential institutional tool that is completely reshaping the situation with long-term care in China, making long-term care an affordable part of reality.

There is a fundamental difference in the supervision path of second-hand residential transactions between Shanghai and Hong Kong. Shanghai is administratively involved by the housing management department, while Hong Kong follows the professional supervision model dominated by lawyers. Between 2020 and 2024, both jurisdictions saw cases of property disputes and loss of funds caused by the lack of verification mechanisms. This study takes the three stages of pre-transaction due diligence, transaction execution and post-transaction rights confirmation as the analytical framework. It compares the supervision rules of the two places across six dimensions—party qualification examination, ownership verification, fund custody, contract authentication, registration effectiveness and dispute relief—and examines the practical problems of each model in combination with representative judicial cases. The study finds that Shanghai relies on the prior administrative verification and compulsory fund custody of the housing management department to ensure the credibility of registration; Hong Kong entrusts the verification responsibility to practising lawyers under the deeds registration system, and the protection of property rights in good faith is comparatively weak. Hong Kong's 2025 Land Titles and Land Registration (Other Amendments) Bill introduces statutory indefeasibility, a HK$50 million compensation fund and monetary compensation in place of compulsory restoration, moving substantially closer to government-guaranteed certainty of property rights. Accordingly, this study proposes a hybrid model of "government core plus professional inspection", suggesting that Shanghai should absorb Hong Kong's independent due diligence mechanism to reduce the administrative burden, and Hong Kong's reform should retain the professional verification layer as a quality filter.

This study focuses on the pricing mechanism of capital protection cap notes and thoroughly examines the differences in the impact of two input parameters, implied volatility and historical volatility, on valuation results and risk exposure. By constructing a composite unified valuation framework of "zero coupon bonds+price differential", the degree of price deviation and changes in Greek letter risk indicators under different volatility assumptions were systematically quantified. The empirical results show that the average pricing of the model based on implied volatility is 1.091, which is 2.25% (1.067) higher than the historical volatility model, and the average absolute difference between the two is 0.024; During periods of extreme market volatility, the difference significantly widened to the range of 0.019-0.037. Further risk sensitivity analysis shows that the Delta and Gamma deviations under the implied volatility scenario are 0.022 and 0.0027, respectively, and the hedging error is reduced by 18.7% compared to the historical volatility model, verifying the high sensitivity of nonlinear structured products to volatility parameters. The research conclusion reveals the amplification effect of volatility selection on the pricing of complex derivatives, providing a theoretical basis for optimizing risk hedging strategies.
